Abstract
The first successful percutaneous transcatheter occlusion technique for patent ductus arteriosus achived by Rashkind in 1977.Transcatheter occlusion with the Rashikind double umbrella device is now widely accepted as treatment for patent ductus arterisus. The reported complications include embolization of the device, psudocoarctation left pulmonary artery stenosis, residual shunts, and mechanical hemolysis. We report two cases of severe hemolysis after occlusion of PDA with Rashkind occluder.
